I take my cellphone with me. How else will I check my FP+ and ADRs? I have a small backpack that I place my wallet, phone, ponchos, sunscreen and few cereal bars in. I also throw in a ziplock bag to put our phones in for water rides like Splash and Kali. It's a toddler size backpack. Sits at my feet during a ride and if the ride is like RnR, then I put a leg through one of the straps. Never had a problem.
